X heads that flow 250 on 416

i run that cam in my 360 with some home ported J heads. i ran 12.22 with a 1.66 60 foot with 3.91's and the jetting was way off. Those X flow descent, if anything for now i would sell your cam and go with something in the 250 @.050 on the intake side. with every thing else up to par i bet you would run very low 11's .
